For a wide landscape photograph where you want everything from the closest foreground element to the distant mountains to be as sharp as possible, which focus technique would an expert employ using a manual camera app?

The expert would employ the technique of hyperfocal distance focusing combined with a small aperture. This method is used to maximize the depth of field, which is the range of distances in a photograph where subjects appear acceptably sharp. To achieve sharpness from the closest foreground to the distant mountains, the goal is to extend this sharp range as much as possible. First, the expert would select a small aperture. The aperture is the opening within the lens that controls the amount of light entering the camera. A smaller aperture, which corresponds to a larger f-number such as f/11 or f/16, increases the depth of field. This means more of the scene, both in front of and behind the precise focus point, will appear sharp. While extremely small apertures like f/22 further increase depth of field, th....
